Coupon shopping

During the coffee break this morning, my collegue at work discuss about Blockbuster coupons which is very useful in shopping. The topic went further through shopping online, which is the cheapest and on bid shopping. Another revealed that she made her shopping online through a group shopping. One can only shop in there if she is a member of the group. To be a member she or he would be invited. I pleaded her to invite so I can be a member in that shopping group. And this weekend I will try shopping online to have more discounts.
